The present application relates to the technical field of communications, and relates to a downlink data receiving method and device, a downlink data sending method and device, and a storage medium. The method comprises: a terminal receives first DCI carried on a first PDCCH that is sent by a base station by means of n antenna panels, wherein the first DCI is used for scheduling m antenna panels of the base station to respectively send downlink data to the terminal, m is an integer greater than 1, and n is a positive integer; the terminal determines, according to the first DCI, a target receiving beam used for receiving the downlink data; and the terminal receives the downlink data by means of the target receiving beam. The method solves the problem of downlink scheduling when multiple antenna panels send downlink data.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The method of claim 1, wherein a number of the at least one default receiving beam is one or more.
6. The method of claim 5, wherein a plurality of transmission configuration indication (TCI) states are carried in the first DCI, and the plurality of TCI states indicate a plurality of receiving beams that correspond to the plurality of TCI states and are used by the terminal for receiving the downlink data.
11. The device of claim 9, wherein a number of the at least one default receiving beam is one or more.
